The Eurotech iOO Now Sells Under the Ergohuman Name, and the Listings Do Not Agree on What Ships
Same chair, newer badge. The headrest is a separate purchase, one bolt holds the back on, and three listings put three different things in the box.
The numbers
- Sold by BTOD as the Ergohuman XTREME, under the iOO part number
- Weight capacity: 275 lb, and Eurotech’s warranty names the same figure
- Seat height: 20 to 23.6 in. Seat depth 15.5 to 17 in, adjustable
- Back height: 21.7 to 23.2 in, a range of 1.5 in, against a claimed 2.8 in of ratchet travel
- Arms: 8-way adjustable, including about 1.57 in of width
- The chair weighs 69 lb, and the same figure is published elsewhere as the shipping weight
- Headrest: not included. A separate part number at about $64 list
- Assembly: 20 pieces, one Allen key, and one bolt holding the backrest
- Named BIFMA standard: none anywhere, from Eurotech or any dealer
Verdict
A pick, on the same evidence as the Elevate. It is in stock at named dealers, Eurotech states a lifetime warranty on every component except upholstery and foam, and the scope is published on Eurotech’s own site rather than left to inference.
I originally refused it for having twenty consumer ratings against the fifty this site asks for. That was the wrong bar. The review threshold exists for things people buy one at a time from shops, and this is dealer-channel furniture that left mass retail years ago. Eurotech has no products in the BIFMA Compliant register, so the standards check does not apply here any more than it does to the Elevate.
One thing to sort out before you order. Put the headrest on the order yourself, because it is not in the box, and buy from the listing title rather than the photographs.
Where the name went
Amazon still titles the listing “Eurotech Seating iOO Chair”. Click the byline underneath and it reads “Visit the Ergohuman Store”, and the brand field in the product details says Ergohuman rather than Eurotech. BTOD goes further and sells the identical part number under the title “Ergohuman XTREME Mesh Ergonomic Chair with Headrest”.
Same chair. Newer badge. This matters when you search, because the reviews and the spec sheets are now split across two names, and the review count on any single listing looks thinner than the chair’s actual history deserves.
One bolt holds the back on
The iOO ships flat, in ten part types and twenty pieces, and the only tool you need is the Allen key that comes with it. That is a good, honest kit. Two arm bolts, four washers, five castors, a gas cylinder, a base.
And one back bolt. A single M8 by 15 mm, quantity one, holding the backrest to the seat.
The Ergohuman, which Eurotech’s own dealers describe as sharing this chair’s design, lists two back bolts on its assembly sheet. The iOO lists one. I am not going to tell you that is dangerous, because I have no test data and neither does anyone else. I will tell you that in 2016 the US Consumer Product Safety Commission recalled a different chair imported by the same company, and the reason given was that the seat could detach.
Check the torque on that bolt when you build it, and check it again after a month. It costs you thirty seconds.
What the iOO actually is
A mesh-backed task chair with a synchro-tilt mechanism, sold for years by Eurotech Seating. BTOD, which stocks it under the part number EUR-iOO-MESH, lists a weight capacity of 275 lb, matching Eurotech’s own warranty, and a chair weight of 69 lb. The seat measures 19.7 in wide with 15.5 to 17 in of depth travel, the back runs 23.2 to 27.72 in tall, and the whole thing occupies 26 by 26 in on the floor at 40.8 to 46 in high.
The adjustment list is long. Synchro-tilt with a seat slider, tilt tension, tilt lock, a single lever handling height and seat depth and tilt lock together, lumbar tension, and a six-way lumbar panel. Warranty runs lifetime on components with upholstery excluded, and BTOD notes foam and upholstery are covered for five years.
What the warranty actually covers
Eurotech publishes its warranty on its own site, and it is worth reading there before you trust a dealer’s summary of it:
“Eurotech’s warranty is limited to the normal use of the product in a forty hour work week and a 275 lb. weight limit unless otherwise noted.”
Lifetime on components. Five years on upholstery and foam. Chairs sold for round-the-clock use run shorter, you need proof of purchase, and the document is dated October 2017.
Dealer pages paraphrase all of that, and the paraphrases drift. One reproduces the sentence with 250 lb in place of 275, sitting under a heading for a different brand entirely, on a page that tells you in its own words to check the manufacturer instead. Another adds an armrest-pad exclusion Eurotech never states. Read it where Eurotech publishes it.
Three listings, three different boxes
| Listing title | Rating | Ratings | Headrest |
|---|---|---|---|
| Eurotech Seating iOO Chair, Black | 3.7 | 20 | Shown in photos |
| Eurotech Seating iOO Chair, White | 3.8 | 6 | Shown in photos |
| iOO Eurotech Office Ergonomic Chair Black Mesh and White Frame (NO Head Rest) | 4.4 | 6 | Excluded, and the title says so |
The third listing is the honest one. Somebody at some point put the exclusion in capital letters in the product title, which tells you the returns were piling up.

Plain links. None of them pays me anything, and I would read the title on each one before ordering.
What it looks like coming out of the box
I bought an iOO in July 2020 and photographed it coming out of the carton. The box is labelled iOO-Blanc, fauteuil resille multifonction dossier moyen, the French description of the white-framed mid-back mesh version. The pictures run from 15:51 to 17:23 that afternoon. Ninety minutes, sealed box to a chair at the desk, and a fair slice of that went on taking the photographs.
It arrives in parts. The five-star base, the castors, the gas cylinder, both armrests, the seat and the back are packed separately, and the headrest comes bagged with its own fixings. The cylinder is pressed into the base by hand.
What the low reviews say
Four critical reviews sit on the black listing. Three of them are about getting something other than what the page showed.
Flaw worth knowing
The headrest catches people repeatedly. One reviewer in September 2018 wrote that they were misled by photos showing the chair with a headrest and were willing to buy the attachment separately but annoyed at the listing. Another in January 2020 hit the same thing and could not reach anyone to sort it out. Two years apart, same complaint.
Flaw worth knowing
Seat material varies and the listings do not make it obvious. A reviewer in September 2023 ordered the mesh seat, received the felt and cushion version, and called the mesh one a favourite chair while returning the one that arrived.
Flaw worth knowing
One October 2024 review reports the supplied bolts fracturing after four years, with the reviewer falling backwards. That is a single report out of twenty, so treat it as a data point rather than a pattern, but it is the kind of failure worth checking your hardware for at assembly.
Who it suits
Worth a look if
You want that adjustment range, you are buying from a listing whose title spells out exactly which variant ships, and a thin review count does not bother you. Sit in one first if you can. At this price the return shipping on a 69 lb chair is its own problem.
What I would look at instead
If the mesh back is what drew you here, the same question came up on the Eurotech Vera page, which went through the same rebrand into the Ergohuman line and ends with chairs you can actually buy today. The reasoning there applies here.
Dealer copies of the warranty do not match Eurotech’s own. Source: Eurotech publishes a 275 lb limit with upholstery and foam excluded. One dealer page reproduces the same sentence at 250 lb under another brand’s heading, and a second adds an armrest-pad exclusion Eurotech never mentions. Whichever dealer you buy from, read the warranty on Eurotech’s site.
No BIFMA standard number, from anyone. Source: what the manufacturer declines to state. Eurotech’s full seating catalogue and its printed instruction sheet contain no BIFMA or ANSI claim at all. Three dealers assert compliance in general terms, one of them misspelling BIFMA. Eurotech has no products in the BIFMA Compliant register, so there is nothing to check the claim against.
One bolt on the backrest. Source: Eurotech’s own parts list, quantity one, against two on the sister chair’s sheet. Read alongside a 2016 recall of a different chair from the same importer, where the stated hazard was the seat detaching.
GREENGUARD is claimed for the whole catalogue and nothing else. Source: Eurotech’s catalogue asserts that all its products are certified, with no certificate number, no expiry and no per-product listing I could find in UL’s directory. Three dealers upgrade this to GREENGUARD Gold, a stricter tier Eurotech itself never claims.
The back height numbers contradict each other. Source: Eurotech’s catalogue, on one page, gives a back height range of 21.7 to 23.2 in and a ratchet adjustment of 2.8 in. That is 1.5 in of range described as 2.8 in of travel.
It has left mass retail. Source: Walmart and Staples product pages now 404, one large dealer marks it no longer available, and another lists it out of stock. It is still sold, but through a long tail of specialist dealers whose spec sheets contradict each other on what is in the box.
Who it fits
Buy it if you weigh under 275 lb, you want mesh with a genuine seat-depth slider and eight-way arms, and you are ordering from a dealer rather than hoping a marketplace listing ships what the photo shows. Add the headrest to the order on purpose. At the lower end of the price band this is a lot of adjustment for the money.
Skip it if you are near or above 275 lb, or if you need a documented standard behind the chair. Nobody publishes one for this model. The Eurotech Elevate is the other Eurotech chair this site recommends, and it is the one to compare against.
Questions
Is the Ergohuman XTREME the same chair?
BTOD sells it under the iOO part number, EUR-iOO-MESH, so the hardware is the same. The name on the box changed.
Is the iOO discontinued?
No. The black version was in stock on Amazon on August 5, 2026, quoted at two to three days to ship.
Does it come with a headrest?
Read the title of the specific listing. One of the three states in capitals that the headrest is not included, and the reviews on the others suggest the photos are not a reliable guide.
What weight is it rated for?
275 lb. Eurotech’s warranty names the same figure, and so does BTOD’s product page.
